Halloween, Otranto, and the Architecture of Terror

As 'spooky season' draws to a close, Dr Peter Lindfield reflects - what does a haunted castle look like?

Perhaps a ramshackle and imposing structure with tall towers, ponderous pinnacles, and undefined spaces backlit by a full moon. The threateningly ill-defined - enough for imagination to fill the gaps - seems to be the ideal catalyst to spark terror.

Visual, of course, this question has also haunted readers for more than 260 years. Ever since Horace Walpole published The Castle of Otranto on Christmas Eve 1764, the novel has inspired visions of dark corridors, towering staircases, moonlit chapels, and mysterious passageways. The first novel to be identified as ‘Gothic’, Otranto cemented many of the themes that came to define the Gothic literary genre and which continue to define Halloween: supernatural apparitions, family curses, ancient prophecies, and mystery. Even so, one of the novel’s greatest achievements lies in an implicit, obscure character: the castle.

The castle in Otranto serves as a remarkably flexible envelope for the novel’s action, yet it remains staggeringly elusive. Readers encounter its galleries, courtyards, chambers, and staircases, but Walpole never provides a complete description of the building. Instead, the castle emerges in fragments, glimpsed through moments of fear, wonder, and supernatural disruption. An incredibly powerful device, by refusing to pin down Otranto’s appearance, Walpole encouraged generations of readers, artists, and architects to imagine the castle for themselves.

My own research on the visualisation of the castle in The Castle of Otranto, published in The Antiquaries Journal in 2016, explored how eighteenth-century artists responded to this challenge. Among the most fascinating are a series of illustrations created in 1796 by teenage artist Bertie Greetheed Jr and pasted into Walpole’s personal copy of Otranto preserved at Yale University’s Lewis Walpole Library (49 3729). Walpole himself considered them the finest illustrations of his novel, praising their ability to capture emotions and supernatural effects that he felt had never previously been realised on paper. On 22 February 1796, Walpole wrote to the artist’s father how:

"I have seen many drawings and prints made from my idle - I don’t know what to call it, novel or romance - not one of them approached to any one of your son’s four - a clear proof of which is, that not one of the rest satisfied the author’s ideas - it is as strictly, and upon my honour, true, that your son’s conception of some of the passions has improved them, and added more expression than I myself had formed in my own mind; for example, in the figure of the ghost in the chapel, to whose hollow sockets your son has given an air of reproachful anger, and to the whole turn of his person, dignity. Manfred in the last scene has an uncertain horror, that shows he has not yet had time to know what kind of agony he feels at what he has done. Such delineation of passions at so very youthful a period, or rather in boyhood, are indubitable indications of real genius, and cannot have issued from the instructions or corrections of a master."

What makes these drawings so compelling is their understanding of architecture as an emotional force promoting monstrous human events and actions.

Gothic interiors loom over their occupants. Arches recede, walls are destroyed, and superhuman-sized figures abound with frail humans dwarfed doorways hinting at unseen spaces beyond the visible. The supernatural visualized in these drawings feel convincing because the architectural setting both prepares us for and amplifies it.

This relationship between architecture and fear lies at the heart of Gothic fiction. Walpole believed that medieval architecture possessed a unique capacity to stimulate the imagination. Gothic buildings, with their dramatic contrasts of light and darkness, their hidden corners and soaring spaces, encouraged emotional responses that more orderly Classical architecture rarely inspired. They could evoke awe, wonder, melancholy, and terror.

Halloween’s return allows Gothic imagination and imagery to once again surface. The Castle of Otranto reminds us that architecture and the architectural imagination has long been one of horror’s most effective yet unspoken tools.
